IMPROVEMENT IN CLOD-CRUSHERS.

Specification forming part of Letters Patent No. 3S, [09, dated April 7,1863.

To all whom it may concern Be it known that I, SrLAs HEwI'r, of SenecaFalls, in the county of Seneca and State ot' New York, have invented anew and Improved Glod Crusher and Pulverizer; and I do hereby declarethat the following is a full, clear, and exact description ot' thesanne, reference being had to the accompanying drawings, making a partof this specification, in which- Figure l is a side view of my inventionadjusted in a position for work. Fig. 2 is a side view of the sameadjusted in a position for being drawn from place to place. In this viewthe cap which covers the toothed cylinder is in section, as indicated bythe line c Fig. 4. Fig. 3 is a plan or top view of the same with the capremoved; Fig. 4, a detached plan or top view ofthe cap.

Similar letters of reference indicate corresponding parts in the severalfigures.

To enable those skilled in the art to fully understand and constructinyinvention, I will proceed to describe it.

A represents a rectangular frame, and B a draftpole attached to it.

B is a shaft or axle, which is secured in the frame A transversely atabout its center.

D is a hollow cylinder formed of two equal parts or sections, c a.,which are placed loosely on the shal't G and allowed to turnindependently of each other. The parts a tof this cylinder areconstructed of cast-iron, and arev each provided with curved teeth b, ofsteel or wrought-iron. These teeth may be secured in the shell ofthecylinder in any proper way, and they are so curved that their concavesurfaces Will face toward the back end of the machine, as shown in Figs.l and 2. rThe toothed cylinder I) is between two cross-bars, c c', ofthe frame A, and to the back cross-bar, c, there are attached at equaldistances apart a series of horizontal plates, E. These plates E areslotted longitudinally, as shown at d, and are secured to the bar c bybolts e, which pass through the slots d and into bar c.

rlhe slots d admit ofthe plates E being adjusted nearer to or fartherfrom the cylinder D, as will be fully understood by referring to Fig. 3.The plates E are so placed as to be between the rows of teeth b, whichhave a circumferential position on the cylinder, as shown in Fig. 3. Theplates E serve as clearers, and prevent the teeth from becoming chokedor clogged-a contingency which would be liable to occur if the groundbe'stii` or clayey.

At each side of the frame A there is a 1ever or bar, F. These leversorbars are fitted on the ends of the shaftor axle C, and are allowed toturn or work freely thereon, and to the lower end ot' each lever or barthere is attached a small wheel, G, as shown clearly in Figs. l and 2,and through each lever or bar F there is made a hole, c. In these holespins d are iitted, said pins passing into the side of l the frame A andsecuring the bars in a vertical position, as shown in Fig. 2. The leversor bars may also be secured in an inclined p0- sition by fitting thepins d into holes in the sides of the frame A above the levers or barsF, as shown in Fig. When the levers or bars F are adjusted and securedin a vertical positidn, as shown in Fig. 2, the cylinder D is elevatedabove the surface of the ground and the machine supported by the wheelsGr G, and may consequently be drawn from place to place with thegreatest facility, and when the levers or bars are adjusted in anoblique position, as shown in Fig. 1, the wheels G G will be above thesurface ot' the earth and the cylinder D in contact with it, the teeth bpenetrating the earth as the machine is drawn along and the peripheryofthe cylinder crushing the clods.

The cylinder D is covered by a cap, H, which is ot semi-cylindrical formand rests upon the frame A. This cap has two shallow boxes, I I, on itstop, one near each end, a space, J, being between the two boxes, whichforms the drivers seat, as shown clearly in Fig. 4. The boxes I I aredesigned to receive stones it' it is necessary to increase the weight ofthe machine in order to make the teeth b penetrate in the earth. Inworking on stili elayey soils this may be necessary.

This machine may be constructed at a reasonable cost, and will operatein the most ecient manner. The chief or distinctive feature 'Iheadjustable clearers E, arranged as is the very ready manner in whiehitmay be shown,in combination with the toothed eyllnadjusted, both forWork and for being transder D, for the purpose specified.
